Abstract : This work consists of two independent parts. Part one deals with the optical and dispersion constants of quartz in the infrared and discussion of a general method of finding optical of dielectrics from two reflection measurements of plane polarized light. A discussion of the pro and con of this method is included and the error in the optical constants found. Part two deals with the construction and operation of a Michelson interferometer. This part includes the operation and properties of cooled bolometers used with the interferometer. (Author)
